Weather warning issued: Remember the last heavy snow?

As weather forecasters predict wintry conditions, we take a look at some of the stunning footage of the extreme snow in 2013 captured by Co Derry man Martin McKenna.

As an amateur astronomer and professional photographer, Martin, from Maghera, has become one of the country’s best-known storm chasers. He has also taken some wonderful pictures of the Aurora Borealis across parts of counties Derry and Donegal.
